Patent number: 9774175Abstract: A device for detecting a flow of air from an exit end of a tube fed into an entrance end of the tube, including a bore having a first section with a first size bore size and a second section with a second bore size, an obstruction located within the bore between the first section and the second section, the obstruction configured to obstruct air flowing from the first section to the second section, and fixing means to fix the device to the tube so that the bore communicates with the exit end of the tube, wherein in use, an air pressure sensor is used to compare air pressure within the first bore section and air pressure within the second bore section, so that a pressure differential is indicative of an air flow within the bore.Type: GrantFiled: September 18, 2009Date of Patent: September 26, 2017Assignee: British Telecommunications Public Limited CompanyInventors: Philip Alfred Barker, Keith Eric Nolde

Patent number: 8720030Abstract: Apparatus for installing a cable into a tube with the assistance of a fluid drag acting on the cable within the tube with an installation device, the apparatus including a driving mechanism comprising a driving surface arranged to contact the cable substantially along the full driving surface length, for driving the cable into the tube, a first measurement device for obtaining a first value indicative of a rate at which the installation device is driving the cable into the tube, a second measurement device for obtaining a second value indicative of a rate at which the cable is travelling through the apparatus, a processor for detecting when the first value exceeds the second value, and for reducing the rate at which the installation device is driving the cable into the tube for the duration when the first value exceeds the second value.Type: GrantFiled: March 31, 2010Date of Patent: May 13, 2014Assignee: British Telecommunications Public Limited CompanyInventors: Philip Alfred Barker, Graham Anthony Laidler, Christopher Nigel Munnings, Ian Hunter, Keith Eric Nolde

Patent number: 6574730Abstract: An authentication system of a terminal on a public switched telephone network provides a security node associated with a local exchange and a network terminal. For one-way authentication, the terminal responds to a call initiation by sending a unique authentication code comprising a number and a secret key encrypted according to a first algorithm, the secret key being specific to the terminal. The security node constructs the expected authentication code from the number, using the first algorithm and a second key which is a function of a terminal identification number, and compares the expected code with the received code. In two-way authentication, the security node responds to the call initiation by sending a transaction number to the terminal encrypted according to a second algorithm. The terminal generates the authentication code as a function of the first algorithm, the secret key and the transaction number. The authentication code is sent back to the security node.Type: GrantFiled: February 11, 1997Date of Patent: June 3, 2003Assignee: British Telecommunications plcInventors: Robert Andrew Bissell, Kevin Paul Bosworth, Michael John Britnell, Peter Maxwell Harding, Richard Middleton Hicks, Jonathan James Kingan, Michael Victor Meyerstein, Keith Eric Nolde, John Rabson, Jonathan Crispin Ranger, David Anthony Roberts, Mark Jonathan Stirland, Richard Paul Swale

Patent number: 6115456Abstract: A remote control system for controlling electrical apparatus in customer premises includes a home control interface for connection by way of network termination equipment, e.g., a telephone socket, to a communications line to a telephone exchange. The home control interface is responsive to signals received from a home control platform connected to the telephone network to control electrical apparatus by way of module interfaces. The home control interface is arranged on demand to transmit signals to the communications line indicative of the current status of each piece of electrical apparatus connected to the system. The consumer may use a telephone to pre-record a definition of the electrical apparatus attached to each connection on the module interface which, when remote control requests are forwarded to the home control platform are used to define the respective switch and to announce its status to the caller.Type: GrantFiled: July 12, 1996Date of Patent: September 5, 2000Assignee: British Telecommunications public limited companyInventor: Keith Eric Nolde

Patent number: 6073174Abstract: A management system provides a remote access service to units of equipment at distributed locations of a communications network. For instance, it can provide automatic meter reading over a PSTN for utility companies. The management system initiates calls over the network to selected units, usually pre-determined, in response to call requests, and can provide considerable functionality such as authentication and batch processing of the request. Conflict with ordinary traffic on the network can be avoided by monitoring for ordinary traffic calls and clearing down any existing conflicting remote access calls or blocking any requested potentially conflicting remote access calls. Uncompleted or blocked remote access calls are automatically re-scheduled by the management system.Type: GrantFiled: March 21, 1997Date of Patent: June 6, 2000Assignee: Bristish TelecommunicationsInventors: Alastair Montgomerie, Jeffrey Edward Deslandes, Robert Malcolm Ball, Dennis John Tricker, Keith Eric Nolde

Patent number: 5920615Abstract: A switching system for inclusion in domestic premises includes a master socket for connection to network termination equipment (e.g., wall socket) and for connection to a plurality of slave sockets each of which may be connected to normal communications apparatus such as telephone, fax or answering machines not shown. On receipt of an incoming telephone call from the network the master socket uses signals which identify the source of the call (calling line identity (CLI)) signals to determine which of the slaves is to be called. Using only four wires (i.e., the normal extension wiring pattern) the master socket can signal individual slave sockets to switch in or out of circuit so that a normal domestic telephony arrangement may be simply and economically converted to include switching.Type: GrantFiled: March 25, 1996Date of Patent: July 6, 1999Assignee: British Telecommunications public limited companyInventor: Keith Eric Nolde
